`uviPsovEMizN-r IN FAUCETS.

Spcclication forniing pai-tof Letters Patent No. 43,421, dated .Tune 27,1865.

ful Improvement ih Self -Glosi'ng Cocksaud` v Faucets; and I do hereby declare that the tbllowing is a full,clear',.and exact description of the same, reference being had to the accom' panying drawings, forming part of this specification, in which- Figure l isa central longitudinal vertical section of a faucet constructed according to my invention. Fig. 2is a transverse section of the same inthe plane indicated by the line a' m in FigLZ. Fig; 3 is a transverse section in the same plane vas Fig. 2, representing the faucet 'with' thec'ap-piece of the stopper and the closin g-sprin g removed.`

Similar letters of reference indicate corre spending partsin the several gures.

This invention is more especiallydesigned -forjcocks and faucets whiehare to be used for sirups or such other liquids as are injuriously aected by contact with the metal 5 but it may be used advantageously for almost all kinds of liquids. The passage of the cock or faucet is lined or fitted with a tube of vulcanized india-v rubber or Aother suitable elastic or lexible material which can be closed by compression 5 and a stopper is so applied inthe place of the ordinary plug or spigot and controlled by a spring as to compress the said tube and close its passage until `the said tube is relieved of its pressure by the pressure of the hand'oriot' any suitable device applied to operate'in a di'- rectionthe reverse of the said spring.

lo enable others skilled in the art toconstruct cocks and faucets according to my invention, I will proceed to describe it by the aid of the drawings. 4

A B .is the shell, made of a form substantially Vsimilar to that of an ordinary faucet or 'stopcock-that is to say, with a longitudinal passage, A, andwitli a transverseorvertical'socket, B', which is like that commonly provided for the reception ofthe plug or spigot, except that it is cylindrical and has cast 'orotherwise pro-V vided in it above thepassage A a diaphragm,

4the socket.

a.. This socket B requires no boring out, as it can be sufcien tl y well formed by coring. C is .the tube of india-rubber which forms a lining to the passage A. This tube may be secured in place by being made large enough and drawn tightly'into the passage A; but Ihave represented it as secured at one end by the insertion ot' a metal thimble, b, Fig. 1, tightly into it.

D el d c is the stopper, made in two pieces,

' one piece et' which, D d d, consists of a hollow cylinder, I), fitted loosely to the upper part ot' the socket B, 'and having two attached legs, d d,which pass through slots in the diaphragm a, ou opposite sides ot the tube C, and the other piece consists simply of a pin loosely inserted through holes in the lower parts ofthe legs el Zender the tube C.

i E is the compression-spring, of spiral construction, its lower end Viittted to a teau, f, on the top of the diaphragm a,wl1ich forms a bearing for the said spring, and its 'upper end tittingsnugly within and pressin gupwardagainst the head of a cap, F,which is screwed into the top of the stopper. The upwardpressure ot' the spring F against the cap presses the stopper upward and presses the pin e against the tubeA in sucll manner as to compress and tlatten the said tube against the diaphragm a (in such manner shown iu Figs. l and 2) as to closethe passage ot' the said tube, and hence the cock or faucet is always kept closed until the stopper is depressed by pressure applied by the hand or by other means on the tcpgof the cap F.

In the depression ofthe stopper to open the .cock or faucet the stopper is prevented from descending far enough to letithe pin e pass below the bottom of the socket B by the head ot' the cap- F -coming in contact with the top Vof the socket- B, and `hence the said pin is always kept in place by being confined Within- When itis desired to` take out the stopper and spring for repair or for any other purpose, the cap F is unscrewed'and removed, and the stopper then drops down to the positionnxshowu in Fig. 3, whicl1 brings tlie'pin e below the socket and permits its withdrawal froin the 2 L l v 485421 holes in the legs d r1. Whenthe pin has been f withdrawn the stopper can be withdrawn from the socket B in an upward direction.

To put the parts together, the stopper is dropped into the upper mouth of the socket B to the position shown in Fig. 3, the pin e in'- serted through the legs d d, the spring E put v into the stopper, and the cap F screwed into the socket. The springE then draws the stop* per up to the position shown in Figs. 1 and 2. What I claim asmy invention, and desire to secure by Letters Patent, is-

1. In combination with aexible lining-tube, C,applied within the passage of a cook orfaueet,

a stopper, the operation of which is so controlled by a spring as to compress and close 'the said tube C automatically, substantially as herein specified.

A2. Theeombinaton of the liexblelining-tube C, stoppei` D d d e, fixed diaphragm a, spring E, and cap F, the whole applied in relation to each other and to a cock or faucet to ooerate substantially as herein specified.
